Soil Moisture Sensor

Soil moisture is the critical parameter in agriculture. If there is a shortage or overabundance of water, plants may die. At the same time, this data depends on many external factors, primarily weather conditions and climate changes. That is why it is so vital to understand the most effective methods for analyzing soil moisture content.

This term refers to the entire quantity of water in the ground’s pores or on its surface. The moisture content of soil depends on such factors as weather, type of land, and plants. The parameter is vital in monitoring soil moisture activities, predicting natural disasters, managing water supply, etc. This data may signal a future flood or water deficit ahead of other indicators.

Gravity: Analog Soil Moisture Sensor

A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It’s an ideal for monitoring an urban garden, or your pet plant’s water level. This is a must have component for a IOT garden / Agriculture. The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold has several advantages over more conventional surface platings such as HASL, including excellent surface planarity, good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points. This soil moisture arduino sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily, while dry soil conducts electricity poorly. This sensor will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.
